a, Schematic diagram illustrating the energy levels of organic layers in the bulk OLED devices. The EQE (b) and luminance (c) responses as a function of voltage for the Ir(ppy)3:CBP reference thin film OLED devices (No etch), in comparison with those having the PEDOT::PSS layers exposed to varied O2 RIE durations (0, 30, 40 and 50 seconds). Performance data are summarized in Table S10. d, Cross-sectional TEM images and EDS map of a representative Nano-OLED device consisting of a 1D linear array of 300 nm wide nanorods with 1 µm periodicity. e, Chemical structures of the materials used in our optimized OLED architecture.
